j an axle 17 on the ends'of which are secured the railwheels-lS and journaled to the outer sills 12 and 13, but is preferably free of the intermediate sills 14 I 25 and 15. The axle at the other end is jouri v sections Ql and 25 are the beams 29 which are placed on edge,as shown in Fig; 2, and.

The side portions 2a and 25- of the platdirectly upon the cross beams16 and are, therefore, at relatively lo'welevation, whereas the central pornaled to the outside jtion 26 of the platform is preferably of raised elevation, ,as indicated in Fig. 2.

F or this purpose it is, supported by suitable vertical struts including corner struts 27 These corner" struts are carried up and curved over ends of the raised platform 26.

Extending al'ongthe two lower platform serve'to. establish rails along the sides'of The engine 30 is supported uponthe of the raised platform section 26. The gas *tanka31/is conveniently supported immediately beneath said raised'platform section as Suitabledrivingmeans must be established between the engine and the axle which carriesthe wheels 22 and 23. Furthermore, it is'desirable to establish a bearingbetween said axle and theframe of the device so as togive proper support'to the central portion of the axle and thus enable it to vided any carrytlie strains imposed by said driving connection. Where such a bearing -is prodeflection of the central portion of the platform will necessarily throw a heavy strain on the axle provided SitlflflXlG be a unitary structure from end to end. In

the absence of any such intermediate bearing, it is very necessary to reinforce the axle shows a fragmentary longitudinal driving pulley for the housing 85 is semi-circular, *1n Fig. 6.

itselfby increasing its size as otherwise it will not be strong enough to withstand the V forces communicated to itw.

According to one aspect of YQIltlO11,I divide said axle inits central portion so as to provide the axle sections 33 and 3a connectedttothe wheels 22 and 23,

respectively. The inner ends of said axle sections may thenbe suitably supported with respect to the frame, and any deflection the present inof the central portion ofthe frame will be I readily compensated for by a slight deflection of the innerends of the axlesections with respect to each other. At thesame time, I have provided a transmission unit directly supported by the frame and which the inner ends communicates directly with of the axle seotions.=

Referring particularly to- Figs. 3 to 8,-in-

elusive the transmission housing includes a box 35 the upper portion of which is closed by a removable cover plate 36. Saidhousing is also provided with aseries ofpedes- 't'als 37 and 38 at; its sides which may be supported upon short cross beams 39 and 40 reaching betweenthe sills 14;and 15, respectively. Preferably Extending across said=lower portion of the housing isa driven's'haft 42, the same being journaled in the end walls of the hously'. Theend portions of the shaft reach beyond said bearings and'rto the outside of the housing and cari'y-a'flanged sleeve and an unflanged sleeve 4E6, respectively, as shown in Fig. 3. Y 7

The inner ends of the'axle shaft sections 33 and 8a are provided with yokes 47 and 48, respectively, which have cup shaped extensions reaching over'the collars-45 and 46. Said cup shaped extensions are slightly larger than the collarswhicli they embrace; a sufficient freedom of movement is thus assured between the parts. Each collar has three outwardly" facing recesses (see'rFig. 6) and the corresponding cup shaped extension has the companion through openings 50. Balls 51 are set into the through openings and reach into therecesses and are held in place by encircling rings52 which may he slipped into place from theoutside. The cup shaped extensionsAfi and 48 have, end flanges 53 and 5st at their innerends, respectively, against which the corresponding rings 52set, as shown'in Fig. 3. Removable locking rings 55 are provided for retaining the encircling rings 52 in place. s

The openings 50 are slightly elongated as is evident from careful examination of Fig. 8, so that a sufficient amount of deflection of the xle shafts with respect to the shaft Therefore, these ball bearing connections constitute in effect unithe lowerportion il ofas indicated ball bearings 4-3 and l l, respectivefame. width; with which ltlihfill gear .66 bfthe idler. othei' end the lay'shaftfifi carries ar' pinioncompanion .60, and its other versal 1 form, resultingrin acorresponding deflection of the casing is, therefore, compensated other casing wall Whereinnit is journaled by a ball bearing61.

Therefore, forward drive of the lay'shaft 56 is sleeve 72 to the right drive is sec'uredby shiftingsaid sleeve" 72 to theleftin said'figure.

. Low speed drive from the lay jsh'aft to the driven shaft 42 is effected by shifting the splined-gear unit '..7l to;

4 and 8.

:.The "upper end of shaft 97-carriesa crank 99" which may be: operated. by a link 100. Saidlink 100 is conveniently connected to a crank 101 on the lower-end of a vertical shaft 102 which reaches up through the raised portion of the platform 26 and has an operating .handle 103- on its upper end. Preferably also the sleeve 93 has a downwardly extending box 104i within which is a spring 105 pressing a ball 106 up against one or the other of a seriesof recesses 107 in the rod Stso as toretain the sleeve 93 in any given set position. v

,The pulley 62 of the driving shaft 59 may be driven in any convenient manner, as by means of a belt 108 reaching from the engine pulley 109. Said belt is provided with a sufficient amount of slack, so that it can run entirely free, but a take up pulley 110 is provided on an arm 111 suitably pivoted to the frame of the car and normally drawn down by the spring 112. Said pulley 110 may be released'in any convenient mannerwhen it is in order to shift desired to slack up .the belt thegears. I 7 brake 'drum' 113inay be conveniently connected to the flange of the collar L5, already referred to, sothat asuitable brake band working on the drum 113 will operate directly on the driven shaft 42 of the trans- 7 mission unit.

In this way thebraking action will be delivered to both ofthe wheels 22 and 23. I

In the modifiedlconstruction illustrated in Fig. 9,'the two axle shaft sections 11% and 115 are connected togetherby a universal joint 116. of construction similar to those already described. Preferably, the inner end of the axle shaft 114 is journaled to the frame sill 117 by a set of roller bearings 118. The inner end of the axle shaft section 114E carries a pulley. 119 which maybe driven by a belt or in other convenient manner. It will be evident that with this construction the deflection of the frame sill 117 will be compensated for by the universal joint 116 without strain.

: In the modified construction of Figs. 10 and 11, the axle shaft section 120 is journaled to the frame sill 121 by a roller hearmg 122 and carries at its inner end the driving pulley 123. The other axle shaft 124 is connected to this pulley by a flexible ring other suitable ma- 125 of fiber, leather or itself connected to the pulley 123,'by a series of three bolts 126 reaching into bosses formed on the face of the pulley, and a hub 127 is placed on the axle shaft section 124, being provided with a series of three lugs 128 which are connected to the ring 125 at points, intermediate between the pulley connections already referred to.

While Ihave herein shown and described only certain embodiments of the features of my present invention, still I do not intend to limit myself to the same, except as I may do so in the claims.

For this purpose, said ring 125 is HIclaim:
